DESCRIPTION
v.in.mapgen allows the user to import Mapgen or Matlab vector maps into GRASS.NOTES
This module only imports data into vector lines.You can get coastline data in Mapgen or Matlab format from NOAA's Coastline Extractor at http://www.ngdc.noaa.gov/mgg/shorelines/shorelines.html.
Matlab vector line maps are simply a series of "x y" data points. Lines are separated by a row containing NaN NaN. Output from Matlab with this command:
save filename.txt arrayname -ASCII
You can import 3D lines from Matlab by exporting a 3 column array and using the -z flag.
